Title: Triphase system for the production of very high unidirectional and continuous currents for radiology purposes
IPC: H02M1/20
Filed: 1926-04-06
Abstract: 250,272. Gorla & Co. Soc. Anon., L., (Assignees of Vanoni, E. P.). April 2, 1925, [Convention date]. Commutator switching-arrangements ; vacuum or low-pressure apparatus, arrangements of. - A system for supplying R÷ntgen-ray tubes with very high unidirectional and continuous currents is characterized by the use of a triphase transformer in combination with condensers and mechanical rectifiers or thermionic valves. The system may include oscillation damping devices in the form of inductances or resistances. In the arrangement shown in Fig. 1 a star-connected transformer is connected to two capacities c<1>, c<2> in series across the ray-tube through a selector with movable contact arms a<1>, b<1>, which are set at 90‹ to each other and are driven by a four-pole motor at half synchronous speed. The voltage supplied to the ray-tube in this arrangement is twice the phase voltage. In a modification of the circuit shown in Fig. 1, the selector a<1>, b<1> is replaced by a set of six thermionic valves arranged as shown in Fig. 3. In this modification, valves having multiple electrodes, for example three anodes and one cathode or three cathodes and one anode, may be used. Modifications are also described employing delta-connected or star-connected transformers and rotary selector switches, the delta and star arrangements supplying respectively voltages equal to twice and to 3.46 times the phase voltage. In all cases, the frequency of the residual oscillation is six times that of the supply current. Oscillations are damped preferably by fitting on the transformer terminals, on the condensers, on the valves, or at various points, an inductance consisting for example of iron wire windings. The Specification as open to inspection under Sect. 91 (3) (a) describes also similar circuit arrangements in which condensers are not included. This subject-matter does not appear in the Specification as accepted.

Filed: 1918-06-04
Abstract: 121,580. Comas y Torres, B., and Comas y Torres, J. Dec. 15, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Shuttle-changing mechanism.-When the weft fails or is substantially exhausted, a rocking bar 21 is moved to position a tappet 27 thereon in the path of an arm 26 on an angle-bar 25 pivoted at its ends on the lay, so that, as the lay moves forwards, the bar 25 is turned and moves a double plate 22, 23 forwards, the exhausted shuttle dropping from the plate 22 on to the rear end of the plate 23. At the same time, the bar 21 acts through connexions to turn a counterweighted lever 17, to which a pin 15 is connected by a chain 16. The pin is lowered and acts on the bevelled surface 5 of a wheel 4 forming part of a three-part wheel slidable against the action of a spring on a rotating loom shaft 3, so that the wheel is moved and a lever 37 drops from the circular portion of a part 6 of the wheel into a recess therein. The lever is connected by a rod 38 to the pivot pin 31 of a bar 30, so that, when the lever 37 drops, the bar 30 is pulled down by a spring 32 and rods 28 connected to the bar 30 are lowered. Cam-pieces on these rods remove a stop 36 from under a fresh shuttle in position above the shuttle box, and a cross-member 33 carried by the rods pushes the fresh shuttle down into the box on the top of the exhausted shuttle. As the lay moves back, the arm 26 leaves the tappet 27, and the plates 22, 23 are pulled back into normal position by a spring, the exhausted shuttle falling through a slot 24 in the plate 23 into a box and the fresh shuttle being supported by the plate 22. The member 33 is raised by the rods 28 and the lever 37, and then a cam-piece on the largest part 8 of the three-part wheel acts through a sliding rod 14 and a lever 12 to actuate a pusher 13, which moves a fresh shuttle from the magazine on to the stop-plate 36 now restored to its normal position. At the end of the changing operation, the three-part wheel is moved back to its normal position by its spring.

When the yarn package 14, Fig. 1, has been completed, the bobbin support 13 rotates to move the package 14 away from a drive roll 15 and to bring an empty bobbin 12' into engagement with the drive roll 15. As the diameter of the fresh yarn package on the bobbin 12' increases, arms 25 carrying the support 13 rise about the axis 26. The drive roll 15 is driven by a change drive 33 that also drives an auxiliary sprocket 35. Sprocket 35 is coupled to a shaft on which is a pulley 36 driving a band drive 37. Band drive 37 is so arranged that it does not drive the bobbin chucks 11', 12' when at the settings shown but only when the support 13 is rotating to move a completed package away from, and an empty bobbin onto, the drive roll 15. Thus, as a full package is moved away from the drive roll 15 it continues to rotate until it reaches the setting shown, and as an empty bobbin is moved towards the drive roll 15 it is brought up to the speed of, or in excess of the speed of, the drive roll 15. Fig. 5 (not shown) is stated to show a doffing device 27, in which a piston 54 operates a rack 51 to turn a pinion 52. Rotation of pinion 52 moves bobbin support 13 in the manner already stated. Each bobbin 11, 12 is held between collars (20), Fig. 2 (not shown), one collar of each pair being spring biassed towards the other but being retractable therefrom by means of a manually operable lever 22. Yarn traverse. The yarn passes through an eye (43), Fig. 4 (not shown), before passing over a traverse guide (41). At the start of a winding operation the eye (43) is moved to one side, by piston operated means (46), to remove the yarn from the traverse guide (41) and into a setting in which it is caught by a roughened strip (47) on the bobbin. When the yarn has been caught by this strip the eye (43) returns to a setting in which the yarn is once again taken up by the traverse guide (41). The fully wound package 14 may be removed from the drive roll 15 and (a) the package reaching a predetermined diameter; or (b) after a predetermined time interval.

Abstract: 1,208,067. Breaking oil emulsions. PETROLITE CORP. 26 Feb., 1968, No. 9276/68. Heading C5E. [Also in Divisions H2 and H3] A process for electrically treating dispersions between electrodes comprises applying to the electrodes a high-voltage potential in pulses, each pulse being of a waveform in which the potential is substantially zero during an initial portion and rises substantially instantaneously to a high value and thereafter follows the normal waveform during the remainder of the pulse. The process is suitable for separating sand or water from crude oil. The fluid to be treated enters a cylinder 10 via a line 26 and is directed against a baffle 28. When high voltage pulses of specified waveform are applied between the perforated electrodes 21, 24, the dispersed particles will coalesce or agglomerate into masses of sufficient size to gravitate from the oil via line 30. The treated fluid is removed via line 29. The pulses are generated by silicon controlled rectifiers 14 which are turned on by a trigger generator 32 at a time t 1  after the beginning of each cycle of the alternating voltage supplied to terminals 11 12, determined by a delay circuit 33. The pulses are coupled to electrodes 21, 24 by a step-up transformer 15. The process may include the use of a predetermined number of bipolar pulses followed by an interval determined, by a pulse circuit 34. Alternatively, complete sine waves may be applied initially and the " chopped " sine waves applied when the current has built up to a predetermined value. The Specification includes performance data. Fig. 2 (not shown) relates to a complete electrical circuit diagram.
